Osteoblastic metastases in renal cell carcinoma
The British Journal of Radiology, 1981Renal cell carcinoma (hypernephroma, renal adenocarcinoma) metastasizes to the skeleton in approximately 10% of cases and characteristically produces expansile lytic lesions (Forbes et al., 1977). Although sclerotic changes may be seen following radiotherapy, osteosclerotic metastases in this condition prior to therapy are virtually unknown (Forbes et ...

Mechano-reception in osteoblast-like cells
Biochemistry and Cell Biology, 1995Response to mechanical stimulation is a basic biological phenomenon. Nearly all cells process mechanical input and respond to it by inducing and modulating biochemical pathways. In organisms with tissues, if the average mechanical load is increased, some tissues can increase their performance and often increase their bulk by cell division. A reduction

Ethanol Inhibits Human Osteoblastic Cell Proliferation
Alcoholism: Clinical and Experimental Research, 1996The habitual consumption of alcoholic beverages is clearly associated with low bone mass and an increased prevalence of skeletal fractures. Microscopic analysis of skeletal tissue from alcoholic patients reveals reduced osteoblast number and suppressed bone formation activity with a relative sparing of resorptive indices.

Calcium in osteoblast-enriched bone cells
Bone, 1992The exchangeability, location, and amount of the total calcium in bone cells were studied in relation to their osteoblastic activity. Cells were isolated from neonatal rat calvariae by sequential collagenase digestion and incubated with 45Ca2+ before or after various treatments. 45Ca2+, 40Ca2+, and DNA were determined on each cell sample.

Immortalized Osteoblast Cell Systems (New Human Fetal Osteoblast Systems)
Calcified Tissue International, 1995Scientists are placing increasing emphasis on developing immortalized cells in culture in order to achieve rapidly proliferating, cell systems with extended lifetimes (e.g., increased population doublings) and normal phenotypic characteristics. As shown in Figure 1, cells undergo a differentiation process, function in the differentiated state for a ...

Estrogen modulation of osteoblastic cell-to-cell communication
Journal of Cellular Biochemistry, 1998Two osteoblastic cell populations, calvarial and marrow stromal cells, were exposed to estrogen derivatives in vitro. The hormonal effect was monitored by following intracellular Ca+2 levels [Ca+2]i and gap-junction communication. We measured fast changes in intracellular Ca+2 levels in response, of these cells, to the steroid hormones.

Osteoblastic Cell Behavior on Nanostructured Metal Implants
Nanomedicine, 2008Surface modifications at the nanometric scale may promote protein adsorption, cell adhesion and thus favor the osseointegration of metal implants. The behavior of osteoblastic cells was studied on mirror-polished (Smooth-SS) and nanostructured (Nano-SS) stainless steel surfaces.The nanostructuration was obtained by anodization.

Key Engineering Materials, 2005
The object of this study was to investigate methods of seeding cells onto porous hydroxyapatite granules with the aim of optimising cell attachment. Two cells types were used; an osteosarcoma cell line, MG63, and human osteoblasts (HOBs) isolated from trabecular bone.

Biotechnology Letters, 2013
Osteogenesis requires close co-operation with angiogenesis to create vascularized bone tissue. In this study, an indirect co-culture model using osteoblasts (OBs), primary endothelial cells (ECs) and Matrigel interlayer was established to understand the impact of each cell type on the other.

Biochemical and Biophysical Research Communications, 1999
We investigated stem cell factor (SCF) expression in osteoblasts because mast cells, which occur ectopically in hyperparathyroid bone, are induced by SCF. Nontransformed osteoblasts and Saos2 or MG63 cells expressed SCF in response to PTH. Western analysis showed only large, cell-associated isoforms, Mrs approximately 40-48 kD.
